We want to make sure that the information that we get from the kernel can
be reinjected without troubles. The kernel shouldn't return an attribute
that is not required, or even prohibited.
Dumping unconditionally NFTA_CT_DIRECTION could lead an application in
userspace to interpret that the attribute was originally set, while it
was not.

When __kernel_clock_gettime is called with a CLOCK_MONOTONIC_COARSE or
CLOCK_REALTIME_COARSE clock id, it returns incorrectly to whatever the
caller has placed in x2 ("ret x2" to return from the fast path). Fix
this by saving x30/LR to x2 only in code that will call
__do_get_tspec, restoring x30 afterward, and using a plain "ret" to
return from the routine.
Also: while the resulting tv_nsec value for CLOCK_REALTIME and
CLOCK_MONOTONIC must be computed using intermediate values that are
left-shifted by cs_shift (x12, set by __do_get_tspec), the results for
coarse clocks should be calculated using unshifted values
(xtime_coarse_nsec is in units of actual nanoseconds). The current
code shifts intermediate values by x12 unconditionally, but x12 is
uninitialized when servicing a coarse clock. Fix this by setting x12
to 0 once we know we are dealing with a coarse clock id.

When an eject request is sent to an ejected ACPI device, the following
panic occurs:
ACPI: \_SB_.SCK3.CPU3: ACPI_NOTIFY_EJECT_REQUEST event
BUG: unable to handle kernel NULL pointer dereference at 0000000000000070

This is becase device->handler is NULL in acpi_device_hotplug().
This case was used to fail in acpi_hotplug_notify_cb() as the target
had no acpi_deivce. However, acpi_device now exists after ejection.
Added a check to verify if acpi_device->handler is valid for an
eject request in acpi_hotplug_notify_cb(). Note that handler passed
from an argument is still valid while acpi_device->handler is NULL.

Currently pgd_alloc has a redundant NULL check in its return path that
can be removed with no ill effects. With that removed it's also possible
to return early and eliminate the new_pgd temporary variable.
This patch applies said modifications, making the logic of pgd_alloc

maps enough memory to get started but using 64K pages rather than 512M
sections with a single pgd/pud/pmd entry pointing to a pte table.

The kernel currently crashes with a low-address-protection exception
if a user space process executes an instruction that tries to use the
linkage stack. Set the base-ASTE origin and the subspace-ASTE origin
of the dispatchable-unit-control-table to point to a dummy ASTE.
Set up control register 15 to point to an empty linkage stack with no
room left.
A user space process with a linkage stack instruction will still crash
but with a different exception which is correctly translated to a
segmentation fault instead of a kernel oops.

When a context is first referenced in the command stream, make sure that all
scrubbed (as a result of eviction) bindings are re-emitted. Also make sure that
all bound resources are put on the resource validate list.
This is needed for legacy emulation, since legacy user-space drivers will
typically not re-emit shader bindings. It also removes the requirement for
user-space drivers to re-emit render-target- and texture bindings.

Since these magic COEF setups are specific to ALC269VB for some PLL

The common clock framework considers NULL a valid clock
reference. This makes handling optional clocks simple, in that if the
optional clock is not available, a NULL reference can be used in the
place of a real clock, simplifying the clock consumer.
Extend this concept to the phy consumer API. A NULL can be passed to
the release calls, the phy_init() and phy_exit() calls, and
phy_power_on() and phy_power_off() and a NOP is performed.

in case it is undefined or its default value is too high (and
communication with PHY is too slow) or too low (and communication with
PHY is impossible). The value of CLKDIV is not specified directly, but

of 2.5MHz. The MAC clock may be specified in the platform data, or in

Gigabit. If the Gigabit PHY comes out of reset with the Gigabit features
set by default in MII_CTRL1000, it will keep advertising these feature,
so by the time we call genphy_config_advert(), the condition on
phydev->supported having the Gigabit features on is false, and we do not
update MII_CTRL1000 with updated values, and we keep advertising Gigabit
features, eventually configuring the PHY for Gigabit whilst the Ethernet
MAC does not support that.
This patches fixes the problem by ensuring that the Gigabit feature bits
are always cleared in MII_CTRL1000, if the PHY happens to be a Gigabit
PHY, and then, if Gigabit features are supported, setting those and
updating MII_CTRL1000 accordingly.

The trigger and events functionality can be useful even if packet
timestamping is not used, but the required PTP clock is only enabled
when packet timestamping is started. This patch moves the clock enable
to when the interface is configured.

Currently the external timestamping code is hardcoded to use the
rising edge even though the hardware has configurable event edge
detection. This patch changes the code to use falling edge detection
if PTP_FALLING_EDGE is set in the user supplied flags.

RCU writer side should use rcu_dereference_protected() and not
rcu_dereference(), fix that. This also removes the "suspicious RCU usage"
warning seen when running with CONFIG_PROVE_RCU.
Also, don't use rcu_assign_pointer/rcu_dereference for pointers
which are invisible beyond the udp offload code.
Fixes: b582ef0 ('net: Add GRO support for UDP encapsulating protocols')
